STOVEIIPE-COLLAR HOLDER.

Application led January 31, 1916.

nails through it into the plaster adjacent the stove pipe opening in the chimney with the result that the plaster around the pipe opening is eventually so far cracked or removed as to present a very unsightly ap-v pearance when the collar is removed.

The principal object of this invention is to provide simple and easily applied means for securing such a collar in position without the use of nails or other damaging devices, said means being also readily released to permit the removal of the collar when desired. In connection with such means cooperating means are provided for holding the pipe in proper position especially where such pipe is of considerably smaller diameter that the thimble.

The invention is embodied in the construction shown in the accompanying drawing, set forth in the following description and finally claimed.

In said drawing- Figure 1 is a vertical sectional view through the breast of the chimney at the stove pipe hole with the improved fastening device set in place.

Fig. 2 isl a view in section of a fraction of a collar on a larger scale showing one of the fastening means removed.

Fig. 3 is a fractional view of the inner edge of the collar to illustrate the socket for the fastening device.

Fig. 4 is. a plan view of the fastener detached from the collar.

In the views 5 designates the breast of a brick chimney having the usual pipe opening in which is fitted permanently an ordinary pipe thimble 6. The character 7 designates a pipe collar which differs slightly from the common form in that it is provided with an annular inwardly extending flange 8 around its central opening and an inwardly bent concentric bead 9. The flange 8 and bead 9 are cut or punched at 13 and 14 respectively and at diametrically opposite points in the pipe opening to form Specification of Letters Patent.

in effect radial seats for the purpose hereinafter explained.

The collar holder consists of an arm l0 of spring metal provided at one end with thimble engaging teeth 11 formed by slantinglyslitting the opposite edges of the arm and bending up the spurs thus produced. These teeth are preferably formed so as to occur in staggered or alternate arrangement in order that the number of thimble engaging positions lengthwise of the arm may be multiplied. The other end of said arm is engaged with the pipe, said end for this purpose being bent to stand at an angle to the arm and form a tongue 12 that enters the radial seats formed by the slots 13 and 14.

15 designates a branch arm riveted at one end to the arm 10 and having its other end curved or formed to engage the stove pipe 16 when the latter is inserted through the opening of the collar. The lioint of the pipe 16 is usually provided with a bead 16a against which the free end of the arm 15 rests to aid in holding the pipe in proper position and prevent its withdrawal except by the application of considerable force.

It is preferable that at least two of the collar holders at diametrically opposite points should be used in securing the collar in place. The holders are applied to the collar before insertion into the thimble, the arms being sprung' toward each other to permit such insertion. Upon the release of the arms they spring outward into engagement with the thimble after which the collar is shoved up as close as possible to the chimney breast. To make convenient the insertion of the arms into the thimble I provide the arm 10 and its pipe-holding branch 15 with a sliding clip 17 adapted to draw the toothed arm inward, as shown in broken lines, Fig. 2, into position to pass freely into the opening of the pipe thimble. When such a clip is employed it can be drawn back to release the toothed arm into engagement with the pipe thimble by inserting the hand through the opening of the collar. l

When it is desired to remove an attached pipe collar the stove pipe is first withdrawn and the tongues 12 of the holding arms merely pulled out of their seats in the collar in a radial direction thereby releasing the collar.

With. this invention it will be observed that the collar is secured by means which engage the inner side and uneXposed portion of the chimney and that there can be no disgurement of the plaster or Wall paper on the face of the chimney.

The forms of the parts of the device are susceptible of considerable modication Without departing from the v`rist of the invention as claimed.

What I claim is:

The combination With a stove pipe collar concentrically slotted to form a plurality of seats extending' radially with reference to `vided at its inner end with teeth to engage a lixed member at the inner side of the chimney opening to prevent the Withdrawal of the arms and collar, and spring arms 15 on said arms l0 to engage the stove pipe to resist its removal.
